Study Notes

Storm Drain System

  • Storm Drain: A plumbing system component that carries rainwater to suitable terminals. Storm water is typically discharged into gutters, public drains, and sent to terminals like canals, rivers, and lakes.

  • Storm Water Disposal: An important plumbing aspect. Improper handling can lead to structural issues like foundation erosion, basement leakage, and property damage.

  • General Rules: Storm drains shouldn't connect to septic tanks or main sewer lines.

  • Splash Pan: Collects water from downspouts, directing it away from the house at a slow rate.

Rainwater Systems

  • Materials: Downspouts can be made of cast iron, galvanized steel, brass, copper, lead, ABS, PVC, or other approved materials, depending on building height and location (interior vs. exterior). Low-rise buildings use galvanized sheet metal.

  • Roof Drains: Should have strainers with sufficient inlet area (1.5x outlet area for dome-type, 2x for flat surface, and watertight connections for drains going into buildings). High-rise buildings need stronger materials to withstand hydrostatic pressure.

Storm Drain Classification

  • Inside Storm Drain
  • Outside Storm Drain
  • Overhead Storm Drain

Water Seal P-Trap Classification

  • Common Seal P-Trap: Has a 5 cm water seal between the overflow and the dip. Offers resistance to normal conditions.

  • Deep Seal P-Trap: Has a 7.5-10 cm water seal, commonly used in areas with extreme conditions like large temperature fluctuations.

Ventilation and Drainage Systems

  • Trap: Prevents sewer gases from entering plumbing systems (hydrogen, hydrogen sulfide, methane, carbon monoxide). Essential for human health.

  • P-Trap: Common, practical trap shape from 32mm to 50mm diameter, used in lavatories, sinks, shower baths, urinals, and drinking fountains.

National Plumbing Code on P-Trap Installation

  • Self-Cleaning: Traps must be capable of complete flushing each operation, preventing sediment buildup.

  • Proximity to Fixtures: Install P-traps as close as possible to fixtures without excessive vertical distance.

  • Short Vertical Legs: Minimize the vertical distance for improved water discharge and to reduce siphonage.

  • Accessibility: Traps should be relatively easy to access for cleaning.

  • Horizontal Pipes: Long horizontal runs are permitted, but should be as short as possible and connected properly.

  • Trap Connections: Overflow pipes from fixtures should connect to inlet of the trap, and each fixture should have its own trap (except for some exceptions like kitchen appliances, connected to the same trap).

Ventilation

  • Ventilation: Part of the drainage system that maintains balanced air pressure.

  • Preventing Problems: Prevents trap seal loss, retardation of flow, and material deterioration.

Types of Ventilation

  • Main Soil and Waste Vent: The main vent for the entire plumbing system, usually located above the highest fixture.

  • Main Vent: A vent line for smaller groups of fixtures.

  • Individual Vent: Connected directly to a fixture, usually below the overflow.

  • Unit Vent: Ventilates two or more fixture traps sharing a single vent, a design similar to back vents.

  • Circuit Vent: Used for multiple fixture traps discharging on a single horizontal branch.

  • Relief Vent: Ventilation for soil and waste pipes, and branches, not just fixture traps.

The Sovent System

  • Innovation: Newer type of water distribution system.

  • Advantages: More efficient, less cost for initial and maintenance, and suitable for high rise buildings.

  • Disadvantages: Susceptible to power loss issues.

Cold Water Supply

  • Water Sources: Rainwater, surface water from rivers and streams, and underground water (wells) are common sources.

  • Impurities: Entrained gases (like carbon dioxide, methane, and nitrogen), dissolved minerals, and organic compounds.
